Yoshino Cherry? ... That's what I noticed when I was up there... just how many cherry trees you had...
Yes, we do have quite a bit of cherry here but the yoshino is one I had never heard of. But it looks like you've nailed it. Thank you. The only place it looks different is on the stem of the leaf. For some reason these are sort of flat but the pictures I find show them round. Still, I think you are right on.
That's a viburnum, not sure of the species... V. lentago perhaps? The flowers are wrong to be a cherry.
My first thought was Linden so I went to have a look at another one. The flowers look the same but the leaves you posted don't seem to have enough of a heart shape to be Linden.
